(g) Rationale: Docks and piers constructed through filling would permanently destroy most ecological value of the area filled and are consequently discouraged. Docks and piers constructed in water with insufficient water depth causes increased turbidity resulting in an adverse impact to special areas and water quality. Docks and piers that maximize sunlight penetration into the water and onto the bottom allow the continuation of photosynthesis by plants underneath the structure. "Spaced planking helps protect loosening of boards during high water levels and wave slap from underneath. In cases where it is demonstrated that the width of the dock must exceed eight feet (for example, fishing piers), the dock or pier shall be sized so as to accommodate anticipated use, while minimizing impacts to special areas by reducing the width of the structure over intertidal and subtidal shallows and wetlands, and by increasing the height of the structure over these special areas consistent with the requirements for public safety. Docks and piers built on pilings will undergo ice heaving, frequently leading to structural damage, during thick ice conditions in areas with significant tidal action. Normal length pilings need to be resunk annually due to ice raising unless some type of water circulation system is installed or ice is broken up daily. Floating docks need to be removed before winter and bottom floatation needs to be serviced annually. Cantilevered docks at a height above winter ice and tidal action levels do not have these problems but have limits in load bearing capacity and must be fastened to a bulkhead.
Jet skis have been gaining popularity among New Jersey's boating public. Jet ski ramps which can accommodate the "dry" docking of these vehicles can be designed to satisfy the needs of the public while minimizing adverse impacts to the environment.
